Other objects and advantages of the invention relating to the particular arrangement is and combination of the various parts will become apparent as the description proceeds. Referring to the drawings illustrating my 1nvention, the scope whereof is defined by the appended claims: i

Figure 1 is aside elevation of a portion of a box car showing one embodiment of my invention applied thereto.

Figure 2 is a side elevation of the fastener on a larger scale.

Figure 3 is a transverse section through a portion of the cardoor andunderframe showlng thefastenerin end elevation.

Figure 4 is a' detail view of rivet bushing or anvil block.

Referring. to the drawings in detail," like parts being designated by like reference characters, the. illustrated embodiment of the locking my car door fastener comprises a housing or casing 1 adapted to be attached to the doorQ of the car by a plurality of rivets or other attachmg means 3. The door 2 1s shown as formed. with a Z-bard, one flange of which extends outwardly of the lower portion of the door 2 and the other flange of which forms a downward extension 5 from the lowor portion of the door, the inner surface of said downward extension preferably being fiush'with the inside of the door, as illus- 3. T he base or side portion 6 of the housing 1 is preferably formed to correspond with the construe tion adjacent the lower part of the door and so, in the present embodiment, is offset as indicated at 7 to provide for the reception of the upper flange of the Z-bar l between the base 6 and the door 2.

Thehousing 1 is formed with a passageway 8 which is longitudinal or" normally upright as indicated and is adapted for the, re-

ception of the fasteningbolt or bar'9,the up- 0 per end of which is preferably headed as indioated at 10 and formed with an apertured lug 11 normally disposed adjacent a similar lug 12 on the'housing 1' for the reception of the usual form of seal (not shown). The

housing 1 is preferably formed with a transverse or normally horizontal aperture 13 for the reception of a fastening rivet let. Said aperture 13 is preferably enlarged to one side as indicated at 15 for receiving an anvil block or rivet bushing 16, said bushing being preferably U-shaped in cross section, as illustrated most clearly in Figure 4-, and adapted to embrace or partially surround the fastening bolt 9. If desired, the side web to the left of the bushing 16 may be omitted so that the transverse aperture is uniform in cross section. The enlarged portion 15 of the aperture is formed of sufficient size to receive the bushing 16 before the fastening bolt is inserted and, when inserted in place, said fastening bolt prevents removal of the bushing. After the bushing and fastening bolt have been inserted in place, as indicated most clearlyin Figures 2 and 3, the rivet 14. is then preferably inserted from the left, as viewed in Figure 2, and headed over at the opposite end as indicated at 17.

in order to facilitate heading over the other end of the rivet, the housing 1 is preferably formed with a transverse wall 18 extending from the base 6 and oining with the outwardly extending portion of the housing, providing for the reception of the fastening bar 9, by a longitudinal wall orweb 19 forming a pocket 20 adapted to receive a bucking bar or the like (not shown), which is held in said pocket against the head of the rivet when riveting over the other end thereof. In order to limit vertical movement of the fastening bar 9, the same is preferably formed with a transverse stop pin 21, the ends of which are received in corresponding grooves 22 and 23 on the interior of the housing to allow raising and lowering of the bar 9 to the desired degree yet normally prevent complete withdrawal thereof.

The lower end of the fastening bolt 9 is received in a bracket or keeper 2d when in fastened position, said keeper being constructed to correspond with the car to which applied and, in the embodiment illustrated, being connected to the web 25 of the adjacent side sill of the car by a plurality of rivets 26. The bracket 2st extends toward the lower edge of the door and is preferably formed Jltll an upright web or flange 27 extending outside of the lower edge of the door 2 or the flange 5 of the Z-bar 4 thereof, thereby pre venting transverse or sidewise motion of the door. The upper edge of said flange or web 27 is continued horizontally as a flange 2S beneath the housing 1 of the fastener and formed with an aperture 29 adapted to register with the fastening bolt receiving aperture of the housing and serve for the reception of the lower end of said bolt when the door is in fastened position. The lower end of the fastening bolt 9 is preferably formed with one or-more apertures 30 normally disposed below the flange 28 of the bracket 2a and adapted to register with a corresponding aperture 31in the upright web or flange 32 of the bracket 2 1 and receive the usual form of sealing means (not shown).

From the foregoing, it will be seen that I have provided a fastener which is preferably applied to the middle of the door at the bottom and replaces the usual fastener which is on the left-hand door post. The bracket 24, which engages thelower end of the bolt 9, replaces one of the usual bottom guides and, therefore, the upright portion 27 may be formed to correspond with the usual guiding portion of a bottom guide. The object in locating the fastener at the middle of the door at the bottom is to prevent anyone, such as a burglar, having access to the car as, when a door is fastened at the left, it is possible to remove one bolt, if the guides are bolted to the car, from each of the. center and right-hand guides, swing the guides down so that they clear the door and then spring the door outwardly enough to gain entrance. With the fastener at the middle of the door, as illustrated, the framing is stiff enough to prevent anyone from springing either the right or left lower corner of'the door. The fastening rivet block or bushing is preferably employed to facilitate heading over the end of the rivet, as it gives a greater thickness of metal to hammer against and avoids damage to the housing 1.
